The Colombia striker, 28, has failed to hit it off at United and Louis van Gaal is not thought to be keen on signing him permanently.

They too have an agreement to buy him for a set fee of £43m at the end of the season.

Falcao's agent Jorge Mendes said: "We don’t know what will happen. What we do know is that he will play for one of the very best clubs in the world next season, whether that is Manchester United or not.
